Apollo has an opt-out sub refund screen out. Since I unfortunately know, first hand, all about this process I'll say this is all incredibly stressful. If you ever had a sub for Apollo, even if you uninstalled it and deleted Reddit, go check it out and at least consider it.

It's probably only a few $s for you but those $s get multiplied by 10s of thousands of subs and end up being real money straight out of Christian's pockets.
